The purpose of this research work is to establish the productive and economic parameters generated by the implementation of the Rational Grazing System Voisin. (RGV), at the cattle farm called La Simona, Pedernales Canton, Manabí Province, over 2014-2015 period, In addition to determining the green fodder production per unit area, measure the stocking density reached by the implementation effect, calculate the milk production per unit area of the cattle sector and determine the production cost of each liter of milk through the implementation of the (RGV). Variables were analyzed in terms of cattle profitability, forage production, stocking density, milk yields and production costs. A comprehensive analytical study was carried out in an area of 72.7 hectares, where the universal laws of the RGV were implemented in an appropriate manner since 2012. The Simona cattle ranch conducted the RGV method for five years in a row, obtaining an evolution in the animal stocking rate from 0.7 livestock units in size/Ha to 2.4 livestock units in size/Ha from 2012 to 2016 respectively. Thus, reflecting that the Basis of the RGV procedure relies on the development of the soil biocenosis, resting periods and pasture use. The results obtained are attributed to the correct RGV practice that allowed organic matter to accumulate in the paddocks from the bovine excrement. It is concluded that through the implementation of the Rational Voisin Grazing System, The Simona cattle farm, experienced an evolution in the green forage production /m2, through the elimination of synthetic fertilizers, agrochemicals and parasiticides of broad spectrum, allowing a natural soil detoxification , with the project implementation in the work immediately and exponentially increased milk yields per unit area, reaching a production cost of 0.35 USD, results achieved by the efficient use of pastures and the holistic integration of existing biotic and abiotic resources in the livestock ecosystem.
